High-frequency Applications of SiC

Compared to conventional techniques SiC-based devices offer:

increased power densities

increased temperature-limit

reduced size of devices

increased performance

Most promising applications of SiC-based microwave electronics are wireless communications and radar, since conventional GaAs-based devices cannot operate at power densities and high temperatures that are demanded i.e. for defence purposes for radar. The same properties allow wireless communication to benefit from SiC. For instance, SiC RF-transistors operate at power densities beyond the theoretical limit of GaAs-based transistors. SiC RF-devices may be used in cellphone base stations.
